The outbreak of a contagious disease can give a facility a bad name-- diseases, from visiting show facilities or training barns, can take a show horse and pull it out of show season with the flu, or strangles, or (fill in the blank). It can take years of being ‘break out free’ for facilities to earn the trust of clients, associations, and competitors again. Forward thinking facilities and those concerned about their future bottom line, use Synbiont® Ag Wash to wash the walls, feeders, waterers and anywhere the horse can come into contact- to help ensure that visiting horses are safe from unwanted pathogens, bacteria or viruses-- and thus secure future shows to keep their good name.

Is Synbiont® Ag Wash Safe For My Animals?
Absolutely. The entire goal of it's development is to keep your horses and animals safe, well and protected from the bacteria, germs and pathogens often found in new environments. Because our products are so effective, sometimes people forget how gentle they are: working with nature to remove harmful pathogens. Horse owners aware of the dangers that new or training or show facilities (which can bring in hundreds of horses during a season) can take control of their horse's health by bringing along Synbiont® to wash the feed areas, waterers, walls and anything their horses might come in contact with. You can also bathe your horse with Synbiont® too--- it 's gentle, yet highly effective at removing pathogens, fungus and helpins small wounds harmful to your horses health-- or coat.

Synbiont ® Ag Wash: "Spray Before You Stay!"

Applying Synbiont™ Ag Wash is a critical, proactive step toward creating your own biosecurity protocol for cleaning your animals, stalls or trailers in helping prevent exposure to deadly diseases. With the recent headlines of EHV-1, this highly contagious disease can affect all breeds and ages via direct and indirect exposure, as well as through the air; most often, the virus can be reactivated during transit or strenuous exercise. Creating a protective, animal-safe barrier against strangles, staph, salmonella, e.coli and other diseases whether at home or on the road cannot be ignored. Avoid exposing your animal to other’s negligence – “Spray before you Stay”.

Can't I Just Use Bleach Or Hydrogen Peroxide And Get The Same Effect?

Nope-- not exactly. Until now, these toxic chemicals have been the only cleaning option for most animal owners. In most cases, these harmful sanitizers can NOT be applied directly to your animals; there are re-entry limitations and only work one time. Synbiont® cleans the host area where pathogens grow by emulsifying dirt and soil; and compromises the cell walls of the pathogen, virus, bacteria or fungi.

Is It True My Horse Doesn't Have To Leave The Stall While It Is Applied?
Correct. There are no re-entry limitations for humans or your horse. Not only can the horse be in the stall during application, there is no harm in the product getting into feeding and water troughs and is safe if licked.

What exactly is Synbiont® Ag Wash?

Synbiont® Ag Wash is an environmentally friendly, multipurpose cleaning concentrate built for large animals and the spaces they live in. One product does the work of several: it serves as a shampoo, a wound rinse, a deodorizer, and a hard-surface cleaner for stalls, trailers, buckets, bits, and bridles. The chemistry was first developed and patented to clean fruits, vegetables, and food-contact surfaces, then adapted for the barn so horse owners get a food-grade-safe option in a market crowded with harsh, toxic chemicals.

What is the chemistry behind the wash?

The active formula is a patented blend of an alkyl sulfonate and an alkyl sulfate. Those ingredients are FDA approved for use on food surfaces intended for human consumption, which is why the company calls the product perfectly safe for washing your hands and for use on hard surfaces. The technology is covered by US Patent 9,295,623, titled "Methods of preventing the transmission of communicable diseases in livestock," and the products are described as laboratory tested and veterinarian approved.

How does Synbiont® Ag Wash actually work?

The wash cleans the host area where pathogens grow by emulsifying dirt and soil, then it compromises the cell walls of the pathogen, virus, bacteria, or fungus. It cleans on contact and is described as staying active for 7 to 21 days, so a single treatment keeps working between cleanings. It also helps deodorize and reduce the ammonia in urine, and on equipment like buckets and bits it requires no rinsing.

Who should use it, and is it safe around horses?
Synbiont® Ag Wash is aimed at horse and large-animal owners, commercial barns, dairies, veterinarians, petting zoos, fairgrounds, and traveling competitors who want a biosecurity barrier at home or on the road. It is biodegradable, non-toxic, and carries zero re-entry time: the horse can stay in the stall during application, and there is no harm if the product gets into feed or water troughs or if it is licked. That makes it a practical choice for sensitive animals and high-traffic environments where new pathogens are a constant risk.

How do you mix it and where can you buy it?

To use, pour one gallon of water into a pump-up sprayer and add one capful (2.5 oz) of Synbiont®, then spray stall walls, floors, buckets, and wash racks liberally; it can also go through hose-end sprayers or spray bottles. The concentrate is highly economical, with one gallon making 50 gallons of finished wash, and it is sold in 32 oz, 1 gallon, 5 gallon, and 55 gallon sizes. The 32 oz concentrate makes 12 diluted gallons and is priced at $36.99; you can order directly through the Buy Now section at synbiontglobal.com, which accepts major credit cards.

The Solution Section (FAQ)

What is Synbiont Ag Wash and what does it do?

Synbiont® Ag Wash is a food-grade-safe biosecurity wash designed to clean animals and any surface prone to host pathogens, viruses, bacteria, and fungus. Active ingredients are a patented, proprietary blend of alkyl sulfonate and alkyl sulfate — EPA-approved and FDA-certified anionic surfactants with high water solubility and high activity at low concentrations. The negatively-charged molecules emulsify dirt and soil while compromising the cell walls of pathogens, viruses, bacteria, and fungi.

Where is Synbiont used in real biosecurity protocols?

Per Synbiont, the product is used in the biosecurity protocols of: veterinary hospitals, fairgrounds, boarding kennels, equestrian arenas, and equine and bovine breeding and boarding facilities. The framing on the road is straightforward: "Spray Before You Stay." Apply Synbiont to your horse, stall, and trailer as a proactive biosecurity step against EHV-1, strangles, staph, salmonella, e.coli, and other diseases — especially when traveling to new facilities or shows where exposure risk is higher.

Is it safe for the horse and the surroundings?

Yes. Synbiont is FDA-approved for food surfaces and safe for washing hands. There are no re-entry limitations for humans or horses — your horse can stay in the stall during application, and there's no harm if the product reaches feeders, water troughs, or gets licked. The product line was developed specifically to fill the environmentally friendly void in a market dominated by toxic chemicals — it's gentle enough to bathe horses with, including for skin issues.

How long does the protective effect last after spraying?

Per Synbiont, normal activity lasts 7–21 days. The applied surface remains active even after the product is no longer visible. To re-activate the coating after the initial dry, simply mist with a fine spray of water — the surface will slightly foam and continue working. This is what creates the protective barrier between cleanings.

How is Synbiont different from bleach or hydrogen peroxide?

Bleach and hydrogen peroxide cannot be applied directly to animals, have re-entry limitations, and only work once on contact. Synbiont can be applied directly to the horse, has no re-entry limit, leaves a surface-active coating that keeps working for 7–21 days, and is biodegradable with no odor. Per the company, the surfactant chemistry compromises the pathogen cell wall rather than just sanitizing the surface — that's a different mechanism than chlorine bleach.

What sizes does it come in, and how far does one gallon stretch?

Synbiont Ag Wash is sold in 1-gallon, 5-gallon, and 55-gallon containers. The dilution ratio is 1:50 — about 2.5 oz per gallon of water — so 1 gallon of concentrate makes 50 gallons of usable wash. Application via pump-up sprayers, hose-end sprayers, or pressure washers all work. There are no expiration limitations on either the concentrated or the diluted product.

Can I use it on my horse's coat for fungal issues?

Yes — Synbiont is used like a shampoo for skin and coat. Per the company, washing with Synbiont® helps reduce fungal issues such as scratches, rain rot, cinch fungus, and improves wound cleanliness while enhancing recovery time. Unlike a regular shampoo, Synbiont leaves a layer of bacterial control that keeps working between baths.

What do facility operators and owners say?

Jeff Kurth, WestWorld of Scottsdale: "We have 9 major arenas and hundreds of horse stalls that we use Synbiont on both for cleaning and infection control." Don Goddard, Ranch Sorting National Championships: "Biosecurity has become a major issue at our shows. Synbiont Ag Wash provides that security and is biodegradable, with no odor on bedding." Chris and Brian, Seven Dogs Grooming and Boutique (Scottsdale, AZ): "All of our groomers have Synbiont at their stations and spray between every grooming." Vickie H. (Martin, TN): "It's my 'go to' remedy for many, many things! LOVE this product." Bill Chester, Out-West: "Synbiont solves many problems in a single bottle."

Is there a re-entry waiting period after spraying?

No. Synbiont® Ag Wash has zero re-entry time, meaning the horse does not need to leave the stall during or after application. There are no re-entry limitations for humans or horses. This is a key difference from many traditional disinfectants.
